Girardi also said that the Yanks are in discussions with the MLB in regards to a roster move with Melky Cabrera. We'll use this post to keep you updated on those developments and separate this stuff from the preview which is going up at 5:30.
Update: 5:26: Again, per LoHud, the Yankees will hear from the MLB concerning their roster move at 6PM.
Update 5:59: Ramiro Pena (not Freddy Guzman as we speculated earlier) will replace Melky Cabrera. Apparently the Yanks value Pena's versatility in the field over Guzman's speed on the bases. Pena has not appeared on the postseason roster at any point up until now but he may be thrust into action early. His best chance of appearing in a game will probably be tonight given that the Yanks are in a National League park and will likely be replacing Jose Molina at some point.
Update 6:27: Interesting tidbit from Mark Feinsand of which I was not aware:
According to the MLB press release, postseason rules provide that injured players can be replaced during the World Series if the severity of the injury, as determined by Major League Baseball, is such that it would require a disabled list assignment during the regular season.
